TiddlyWiki

Now this is cool. It’s TiddlyWiki, which is “a reusable non-linear personal web notebook.” It’s hard to describe, as the front page of the TiddlyWiki site is itself a TiddlyWiki. The idea is you have a single HTML file, laden with all kinds of javascript, that allows you to make notes from within the browser itself, storing everything you type into that single HTML file. Useful for jotting down ideas, for later re-arrengement into something more coherent. Each entry is like a notecard. Or something.
